So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk.

I think people tend to be worried about every new technology that comes along.

With a generation of younger folks who have thrived on the success of their companies, there is a big opportunity for many of us to give back earlier in our lifetime and see the impact of our philanthropic efforts.

It is really important for us that people understand what the strategy is and that the real approach is to make everything social, not to build a vertical approach.

The biggest risk is not taking any risk.

When I was in college I did a lot of stupid things and I don't want to make an excuse for that. Some of the things that people accuse me of are true, some of them aren't. There are pranks, IMs.

It used to be the case, like, you'd switch jobs, and then maybe you wouldn't keep in touch with all the people that you knew from that old job. Just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.
